What is Outlook PWA?
A PWA (Progressive Web App) is a website that can be installed and used like a normal desktop application. Microsoft Outlook on the web can be installed as a PWA, giving you an Outlook experience that looks and feels like a desktop app without requiring the full Outlook desktop software.
Using the Outlook PWA is particularly useful if you access your work email from a personal or shared computer. Because the application runs primarily through your web browser, it stores significantly less data on the device than the full desktop version of Outlook, helping to keep work information separate from personal data. Some temporary data may still be cached locally to improve performance, but Outlook PWA does not maintain the same offline mailbox data files used by the desktop application.
Microsoft 365 email accounts are business-class email services and some Microsoft 365 licences do not include the Outlook desktop application. If your Microsoft 365 subscription includes the Microsoft Office desktop apps, you can choose to use the full Outlook desktop client. However, if you have a licence such as Exchange Online Plan 1 or Microsoft 365 Business Basic, Outlook PWA provides an excellent desktop-like experience without requiring an additional Outlook licence.
Benefits of Outlook PWA
- No software installation required beyond your web browser
- Microsoft Office Desktop Apps licence not required
- Works like a desktop application

- Reduced local storage of company email data
- Available on Windows, macOS, and Linux
- Ideal for personal or shared computers
